    Does anyone have insight on what these errors mean?

    IL2CPP error for method 'System.Void UnityEngine.UI.ObjectPool`1::Release(T)


    [ERROR] FATAL UNHANDLED EXCEPTION: System.ArgumentException: An element with the same key already exists in the dictionary.

    Can you provide more details about the error? Which platform are you building? Is there a call stack in addition to the error message? Does this error occur while the project is being built or when the player is running? I think these answers will help us narrow down the cause of the issue. Thanks!

    Its a ios build and android builds fine. The build did not complete and the cloud build logs explain little beyond something went wrong with IL2CPP.

    Is this error from a WebGL build? It might be good to try it locally and see is the problem occurs. Maybe there is some issue on the cloud build side then.

    I am not sure what you mean, how did WebGL enter this?

    Sorry, that I was my mistake. I thought you said that iOS and Android built fine. I assumed that this must be a WebGL build then. Re-reading your message indicates that this is an iOS build.

    Can you try that build locally?

    We tried on a local mac and it did build successfully but crashed at startup, I do not know if the issues are related.

    On cloud build is there any way to get more info on what the build errors mean?

    I don't know enough about cloud build to say where additional logs might be. I've pinged our cloud build team though to have a look a this thread.

    After talking with our cloud build team, it looks like you can access the full log. I'll send you the link privately.

    That was the log I was already using to get the errors I posted but it does not mean anything to me other than IL2CPP had some sort of internal error.

    Ok, so there is no other data in the log other than what you posted here? If so, we need to expose something else from cloud build, that information doesn't look like enough. I'll talk to the cloud build team and see what we can do.

    Actually, it may be best to submit a bug report for this. Something looks to be wrong on our side (although I'm not yet sure where). Can you file a bug report for this issue?

    Do the cloud build team have the ability to view the logs?

    I am not sure what to file other than IL2CPP and cloud build need to throw exceptions with more useful messages than "key not found" or "il2cpp.exe did not run properly".

    We did eventually get the ios build to work but I have no idea why.

    The log should have more information then that. Specifically, there should be a call stack from il2cpp.exe in the log file below the error message you reported.

    In any case though, did this project then build for iOS on cloud build correctly? If so, we may still have a problem, as the behavior should be consistent.

    So looking at the stack trace it seems IL2CPP is repeatedly putting nulls into a dictionary. Could you ask the IL2CPP people to take a look at this since I have no repo case to file a useful bug report.

    I do work on IL2CPP, so you're in the right place. :)

    Unfortunately though I can't tell too much about the cause from this call stack alone. If you get back to a point where this happens again, and you do have a way to reproduce it, please ping me, and I'll gladly have a look at the repro project.

    We can't build to IL2CPP, too. Our project is already big with lots of asmdef files. When building, it get's stuck in "Building native..." or something like that. The build already took 2 hours but it's still not done which leaves me no choice but to kill it.

    I can give you read access to our Bitbucket repository so you could try it on your end. Do you have a Bitbucket account?

    Please drop us a bug report, and include instructions on how to access the project. We can get it via BitBucket using a specific account, that should not be a problem.
